Outstanding Warranty Options

CertainTeed backs its commercial roofing systems with the confidence of three warranty choices:

Limited Product Warranty

NDL Roof Membrane Limited Warranty*

Full System NDL Limited Warranty*

Owners and specifiers who choose the NDL or Full System NDL warranty options have the added security of manufacturer involvement in the sometimes difficult process of contractor qualifying and workmanship inspection. Consult with the roofing contractor and your CertainTeed commercial roofing territory manager to decide which CertainTeed warranty is best for your building or project.

*NDL warranties are not available on all specifications and are only available through CertainTeed Gold and Silver Star Contractors

CoolStar roofing products are more energy-efficient than standard roofing products and exceed ENERGY STAR® and California Title 24 standards.

To meet ENERGY STAR standards, a low slope roofing surface must have a solar reflectivity of .65 (meaning it reflects 65% of the radiation away from the surface and absorbs 35%).

In general, an ENERGY STAR-labeled product can help reduce energy costs by as much as 30%.

The state of California has an even tougher requirement for a "cool" or energy-saving roof called Title24. To comply, a low slope roofing surface must have an initial solar reflectivity of .70 and thermal emittance of .75. CoolStar roofing products surpass both of these important, industry-recognized standards.
